Car Door Safety Warning Lights
Make every open door easier to spot—especially at night. These compact LED Car Door Safety Warning Lights flash automatically when the door is opened, helping alert approaching drivers, cyclists, and pedestrians to the open door.
With a bright 5-LED strobe, the light rapidly flashes during the first 6 seconds for maximum visibility, then continues operating before automatically switching off after approximately 180 seconds. The built-in sensor and wireless design mean no wiring, drilling, or complicated installation—simply attach it to your car door and you're ready to go.

A simple upgrade that adds extra visibility whenever you open your car door—day or night.
Prevent dangerous rear-end accidents the second you open your car door with high-visibility, automatic warning lights.
Tool-free magnetic installation: Attaches securely to any metal door frame in seconds without wiring, drilling, or vehicle modifications.
Smart auto-strobe technology: Instantly triggers a rapid, high-intensity flash to alert approaching drivers, then automatically shuts off after 3 minutes to conserve battery life.
Ultra-slim daily protection: The compact 28mm profile ensures your door closes seamlessly while running on a standard, easily replaceable CR2032 battery.
Triggers an immediate strobe flash the second you open your door, alerting approaching vehicles in the dark to prevent side-impact collisions.
Snaps directly onto the metal frame of your car door with a strong internal magnet, requiring no tools, drilling, or wiring to secure it in place.
Fires a rapid strobe pattern for the first 6 seconds, cutting through poorly lit streets to grab the immediate attention of passing cyclists and drivers.
Measures only 8mm thick, allowing the device to sit flush against the panel so your door closes and seals exactly as it did before.
Operates entirely on a single coin battery and shuts off automatically after 3 minutes, saving power when you need to keep the door open while unloading.
Opening your car door immediately triggers a rapid strobe sequence that forces approaching drivers to steer clear and prevents sudden side-impact collisions in the dark.
Targeted 6-Second Rapid Alert: The instant the door parts from the frame, the built-in magnetic sensor fires a high-intensity flash sequence for exactly six seconds, breaking through low-light conditions to catch the eye of rear-approaching traffic before they get too close.
Zero-Wire Flush Mount: Measuring just 8mm thick, the flat ABS housing adheres directly to the inner door metal, allowing the heavy car door to slam shut smoothly without pinching bulky external wires or requiring permanent drilling.
Auto-Shutoff Battery Preservation: Instead of draining power while the door stays open to unload cargo, the internal timer completely cuts the lights after 180 seconds, preserving the standard CR2032 battery for months of daily commutes.
